Cinderella Fairytale Wedding

I am helping plan my neice`s wedding. I have ordered little miniature coaches and the glass slippers, but I really can`t decide on a nice centerpiece for the shower. This would probably be used on the bride`s cake table also. The church also has 10 windows that are recessed that need decoration. There are two planter type boxes on each side of the church that need something. Any suggestions anyone? Also, does any one know where I can buy the little ceramic mice? my email is retarobertson@yahoo.com
